Verdict

The De'Longhi Pinguino PACEM77 Silent is a 3-in-1 portable air conditioner featuring a 9,000 BTU (2.1 kW) cooling capacity, an 800 W input power, and Class A energy efficiency (2.6 EER) optimized for rooms up to 70 m³. Its main characteristics include an eco-friendly R290 refrigerant gas, a soft-touch button interface, a 24-hour electronic timer, a 3-speed fan (340–400 m³/h airflow), and a robust dehumidifier capable of removing up to 40 liters of moisture per 24 hours. The main pros of this model are its automated condensate recirculation system which minimizes the need for frequent manual draining, pre-assembled folding castors for easy room-to-room transit, and an included 1500 mm window exhaust kit for quick setup. However, its notable cons include a substantial physical weight of 30.5 kg, a loud maximum sound power level of 63 dB(A) despite its "Silent" labeling, and a bulky body footprint measuring 425x345x700 mm.

Summary of the review

DeLonghi PAC EM77 test and review - Testaankoop

The DeLonghi PAC EM77 is rated as an exceptionally user-friendly mobile air conditioner, featuring clear manual instructions (5 stars) and good overall ease of use (4 stars). The unit, which excels in temperature distribution and standby energy efficiency, is limited by low overall efficiency and significant operational noise. A 2-star rating for noise during normal and low-power modes makes it less suitable for quiet environments, despite acceptable performance at maximum capacity.
